The point of my response was directed towards the individual's perception of "meaningless parting." I offered perspective that the partying isn't meaningless at all, but is a very good way to build camaraderie with future professionals, and that, perhaps, his negative perceptions of his peers may well have an effect on his peers perception of him. Likewise, whether or not the individual in question does pursue other relationships/hobbies doesn't undermine the hypotheticals and generalizations highlighted, being that "meaningless partying" is, in my opinion, far more beneficial than isolating oneself in professional school. You may disagree. Regarding ethics, "laughing all the way to the bank" implies nothing about ethical or professional misconduct; the two are not mutually exclusive so long as professional/ethical conduct are prioritized over self-interest; regarding this convo, it's an extraneous point.
